Video has emerged showing the crowd at pastor and televangelists’ John Hagee’s Cornerstone Church in San Antonio singing the thinly veiled attack on President Joe Biden during the controversial “ReAwaken America” conference.

Another clip shows that the “let’s go Brandon” chant—which Donald Trump supporters use as a direct replacement for the “f**k Joe Biden” chant—did not erupt spontaneously, but instead was led by those on stage.

From November 11 to 13, the Cornerstone Church held the controversial “ReAwaken America” conference in which Trump allies and other conservative figures pushed COVID-19 vaccine skepticism and conspiracy theories about the 2020 election.
